摘　　要：结构完整性是决定航空结构安全与寿命的主要因素,也是制约新材料、新结构、新工艺等有望提升航空结构效率的新技术在航空领域应用的重要问题。明确并提升先进材料及工艺的结构完整性性能有助于航空结构进一步利用新材料、新结构、新工艺的优异特点,实现航空结构更可靠、更高效、更经济的目标。本文主要梳理了航空疲劳与结构完整性国际委员会(ICAF)成员国近年在这一领域中的主要工作和所取得的成果,重点介绍了近年来在新材料、新结构、新工艺的疲劳寿命方面国内外各领域学者所取得的新进展,以促进国内航空材料与结构工作者持续关注航空疲劳与结构完整性方面的问题与进展。在此基础上,结合近年来材料结构和工艺领域取得的突破和航空结构性能的新需求,对新材料、新结构、新工艺的结构完整性研究和未来航空结构的设计工作提出了建议和展望,以促进航空结构完整性的研究和性能的进一步提升。Structural integrity is not only the primary factor determining the safety and lifespan of aeronautical structures, but poses significant challenge to the application of novel materials, structures, and techniques in the field of aviation. Clarifying and enhancing the structural integrity performance of advanced materials and structures can facilitate the utilization of the outstanding capabilities in aviation structures, thereby achieving more reliable, efficient, and economical aviation structural goals. The present paper systematically reviews the main achievements and recent work conducted by member countries of the International Committee on Aeronautical Fatigue and Structural Integrity(ICAF) in the past years of this field. Moreover, this paper introduces the recent advancements made by scholars from various fields in terms of the fatigue life of advanced materials, structures, and techniques, to stimulate continuous attention of researchers in aeronautical structural field towards the progress and issues on the aviation structural integrity. On this basis, combining with the extensive progress made in material, structural, and techniques domains in recent years, along with emerging demands for aeronautical structural performance, this paper also presents suggestions and prospects for the fatigue research of novel materials, structures, and techniques, as well as the design of future aeronautical structures, in order to further promote the development of this field.
